Three fiber loop sensors combined with four trip relays provide expansive sensing coverage and rapid isolation when a fault is detected. Business impact: this arrangement improves fault discrimination, minimizes arc flash energy release, and shortens downtime by preventing unnecessary trips. Application: ideal for multi‑zone panels and switchgear rooms where precise arc flash protection is required without sacrificing system availability. Voltage and power range flexibility is a core capability: 80-265 Vac/dc input and a 120-240 Vdc, 125-250 Vac supply enable operation across global facilities. Business impact: installers can retrofit or scale protection without reconfiguring upstream supplies, saving wiring effort and reducing project risk. Application: suitable for new builds and upgrades in distribution panels, machine rooms, and control panels across industries. Panel mounting and compact form factor streamline installation: dimensions 6.89 in length, 6.18 in height, 1.85 in width, and weight of 1 lb. Business impact: lighter, smaller devices reduce enclosure space requirements and simplify handling during installation. Application: fits standard rack or panel spaces in industrial control panels and electrical cabinets. Operational reliability is supported by UL Recognized and cUL Recognized certifications and a defined warranty: Eaton's policy offers one year from installation or eighteen months from shipment. Business impact: regulatory alignment and predictable maintenance budgeting reduce total cost of ownership. Application: procurement teams can specify with confidence for facilities in North America and global sites. Compatibility with Light Sensing Inputs and Normally Open trip contacts aligns with established safety schemes and zone-selective interlocking strategies; although it provides zero analog inputs or sensing, its digital outputs naturally support panel protection logic. Business impact: simplifies integration with existing PLCs and safety interlocks, lowering integration risk. Application: arc flash protection in manufacturing cells, packaging lines, and process equipment.

FAQs
Plan for panel mounting in standard electrical enclosures, ensuring adequate space for a 6.89 in L x 6.18 in H x 1.85 in W unit and a 1 lb weight. Use the normally open trip contact configuration with fiber loop sensor wiring and the four built-in relays. Verify the panel has a 120-240 Vdc/125-250 Vac power supply and 50/60 Hz compatibility, and confirm UL/cUL recognition for compliance.
Key specs include voltage rating of 80-265 Vac/dc, power supply range of 120-240 Vdc and 125-250 Vac, and 50/60 Hz operation. The device features four digital outputs, zero analog or current sensing inputs, and light sensing inputs with three fiber loop sensors. The configuration supports arc flash protection within panel and control environments.
Yes. The EAFR-102 is designed as a fiber loop sensor unit with up to three fiber loop sensors and four trip relays. It provides light sensing inputs and a normally open trip contact, while offering zero analog inputs, zero analog outputs, and zero current sensing inputs. This makes it ideal for targeted arc flash protection in fiber-enabled protection schemes.
The device is UL Recognized and cUL Recognized, signaling compliance with key North American and international safety standards. These certifications help streamline regulatory approvals during installations, expansions, and upgrades, particularly in facilities that require cross-border equipment sourcing and stringent safety programs.
Advantages include a compact panel-mount form factor, straightforward wiring for fiber loop sensors, and a light-sensing input design that reduces unnecessary trips. Maintenance benefits come from a clear warranty window of one year from installation or eighteen months from shipment, along with robust UL/cUL certifications. These factors collectively reduce downtime, minimize commissioning effort, and improve lifecycle cost of ownership in arc flash protection projects.
